Greenhouse Gas Emissions Accounting for ADB Energy Project Economic Analysis

This guidance note focuses on economic analysis of greenhouse gas emissions effects of projects in the energy sector. Recommendations seek to make practices consistent across cost-benefit calculations.

Reporting of emissions of energy projects outside of economic analysis uses a different point of comparison (a baseline scenario) than does economic analysis (a without project scenario). As economic analysis needs to use a consistent set of scenarios across benefit streams, the note recommends and illustrates the use of a without project scenario for calculating emissions effects in project economic analysis.
